The aim of this study was to evaluate the consequence of changing land use from agriculture land to other use purposes with respect to OCPs non-cancer and cancer risk on human health, based on concentrations of DDTs and HCHs in soils collected from 55 locations representing 12 different land use types. There were no non-cancer risks of DDTs and γ-HCHs on adults and children, and there were very low cancer risks of DDD, o,p'-DDE, DDT, α-HCH, β-HCH, γ-HCH based on their total concentrations in all samples. Nonetheless, there were significant correlations of DDT to its metabolites (DDE and DDD) (r = 0.506 and r = 0.648) and DDE to DDD (r = 0.438) both at p < 0.01. OCP levels should be routinely monitored in different environmental media and food in order to verify whether there is fresh input. Their potential risks on human health should also be assessed.

Common carp () is extensively cultured and widely consumed in Heilongjiang Province, China. Due to the proximity of freshwater ponds to agricultural cultivated areas, these aquatic systems are inevitably influenced by the historical application of organochlorine pesticides (OCPs), due to their prolonged half-life and resistance to degradation. Gas chromatography-tandem mass spectrometry (GC-MS/MS) was utilized to quantify the levels of hexachlorocyclohexane (HCHs) and dichlorodiphenyltrichloroethane (DDTs) in the muscle tissue of cultured common carp.

With the phase-out of legacy persistent organic pollutants (POPs), the ocean's role is evolving, potentially acting as both a reservoir and a source. This study investigates the air-sea fluxes of the first banned POPs, such as organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), using literature from Web of Science up to 2023. OCP and PCB concentrations in air and seawater show significant spatiotemporal variability.

Worldwide forest fires have occurred frequently in recent years, a result of which may be the emission of so-called "legacy" organochlorine pollutants (OCPs) accumulated in forests. However, few studies have measured the emission factors (EFs) of the toxicity of the OCPs from forest fires. In this study, the EFs of vegetation burning were observed in forests along the altitudinal gradient from 1000 to 4200 m, and the EFs of ∑DDTs (dechlorodiphenylthrichloroethanes), HCB (hexachlorobenzene), ∑HCHs (hexachlorocyclohexanes), and ∑PCBs (polychlorinated biphenyls) were 2050 ± 1175, 379 ± 409, 48 ± 51, and 65 ± 59 ng/kg, respectively.

The Arctic region, including Svalbard, faces unique environmental challenges from the presence and persistence of organochlorine pesticides (OCPs), pollutants known for their long-range atmospheric transport and potential local sources. In Svalbard, the melting of sea ice and glaciers due to climate change may release OCPs trapped over decades, while human activities in the area could contribute additional local contamination. This study aimed to identify and quantify different sources of OCPs in soil and marine sediments at Svalbard.

Fish is an important food item in the diet of humans, whereas it is also a major source of exposure to toxic chemicals. Persistent organic pollutants (POPs) and mercury (Hg) are known to have hotspots of contamination across the coast of Pernambuco, Brazil. This study investigated organochlorines and Hg in muscle samples from respectively 17 and 14 individuals of the stingray Hypanus berthalutzae - a fishing resource used to prepare a traditional dish in the local cuisine.
